Answer:
the expression is: 
and 2730 different ways are possible.
Step-by-step explanation:
In the given question we have to choose a president, vice
president, and secretary.
Permutations are used when order is important so, as in the given question order is required. We would use permutations
The formula used is:
where:
n=total number of objects
r=number of objects selected
In our case: n=15, r=3
Putting values and finding the answer:

So, the expression is: 
and 2730 different ways are possible.
Answer:
we can conclude that:

Step-by-step explanation:
Given the expression

Let us factorize the expression

Apply the exponent rule: 

Rewrite 12 as 4 · 3

Factor out the common term 3x



Therefore, we can conclude that:

Answer:
x + 4
Step-by-step explanation:
(x - 9)(x + 4)
FOIL
x^2 + 4x - 9x - 36 = x^2 - 5x - 36
